Singly Linked list is a data structure in which each node contains a data field and next(pointer) field. And the next pointer contains reference to the next node in the list.
ptr1(1200) ptr2(1400) ptr3(NULL)
+-------------+ +-------------+ +---------------+
| 25 |ptr1 -|---->| 30 | ptr2 -|---->| 40 | ptr3 -|--->X
+-------------+ +-------------+ +---------------+
n1(1000) n2(1200) n3(1400)
n1(node1), n2(node2) n3(node3) - nodes
ptr1(1200) - pointer to node2 with address 1200
ptr2(144) - pointer to node3 with address 1400
ptr3 - pointer of the last node always points to NULL.

How to create a node in linked list?
Dynamically allocate memory for the new node, fill the given data in it and return the new node to the caller.
struct node createNode(int data) {
struct *newnode = (struct node *)malloc(sizeof (struct node))
newnode->data = data;
newnode->next = NULL;
return (newnode);
}

+-------------+ +--------------+ +--------------+
n1(1000) n2(1200) n3(1400)
Insert a new node(n4) after node n2.
Traverse the list from the head node(n1) to the node(n2) after which the new node needs to be inserted.
n4 = createNode(50);
n4->next = n2->next;
n2->next = newnode;
Note: n4 is the new node here

n1(1000) n2(1200) n4(1500) n3(1400)
Traverse the list from the head node(n1) to the node(n2) that is present previous to the node(n4) which needs to be deleted.
temp = n2->next; // temp points to node n4
n2->next = temp->next; // n2->next points to node n3

How to search a node in a linked list?
Traverse the list from the head node(n1) until we find a node with the given value. If we have traversed the entire list and could not find a node with the given value, then the given data is not present in the list.
struct node * searchNode(int data) {
struct node *temp = n1; //n1 is the head node
while (temp) {
if (temp->data == data) {
printf("Data Present\n");
return temp;
}
temp = temp->next;
}
return NULL;
}
